Default Unknown Driver, Service 4wd, Lost all gauges except RPM and MPH

I was on the way home from work yesterday evening, and suddenly my dash started beeping and the alert “Unknown Driver” flashed on the display along with “Service 4wd”. I also noticed that my radio cut off and all my gauges except the speedo and rpm quit working... I scanned for codes and got a P0370, P0380, and there were a few other which I can post up at lunch time as I am at work right now. Anybody have any ideas on where to start? I plan on looking into it this evening after work
